The energy transition will succeed only if the majority of our electricity is generated from renewable energy sources in the future. However, this poses a major challenge: How can energy suppliers that depend on the weather reliably and continuously feed electricity into the utility grid? SMA offers a range of technical solutions that not only ensure grid stability but also open up new sources of revenue with secure returns for power plant owners and operators.<\/strong><\/p>\n

Continuous supply of electricity \u2013 even in volatile times<\/h2>\n

Water, sun and wind levels are inherently variable. The amount of green electricity generated fluctuates depending on the weather conditions. For a sustainable energy transition, however, there are no alternatives. The only way to mitigate climate change in the future is to ensure that fossil energy suppliers are replaced by renewable ones and that our electricity comes entirely from carbon-free sources. From the perspective of consumers, this is not an immediate problem because wind, solar and water energy is capable of covering all our energy requirements. To bridge periods of low sunshine or wind, energy can be stored in large battery systems. This compensates for energy fluctuations and ensures that green electricity is available around the clock, whatever the weather.<\/p>\n

Grid forming<\/strong> ensures stability of power grids<\/strong><\/h2>\n

Switching to renewables entirely, however, poses a fundamental challenge for transmission grid operators. Gas-fired, oil-fired, coal-fired and nuclear power plants, both generate energy and provide grid forming capability. The synchronous machines at the power plants ensure a stable grid voltage with a uniform frequency thanks to their inertia. This ensures a continuous supply of electricity even if the power generated at a specific moment in time cannot cover demand. This imbalance can arise as a result of, for example, generator or large load failures or large-scale grid separations.<\/p>\n

If decentralized renewable energy producers assume the energy supply work of centralized power plants, they will also have to form and stabilize the power grid. This concept of grid forming is also indispensable for wind, solar and hydroelectric power plants because, in most cases, they need to transport the generated electricity over long distances from remote locations to consumers. The risk of failures, grid separations and, in turn, power imbalances is especially high when long transport distances are involved. This means that grid operators have to ensure grid stability as well as the supply of electricity.<\/p>\n
